Application filed August 3 who 12a, it may concern:

1 known that l, Vr' AI-JJER G. Kisser, a citizen of the United States, of Rochester, in the county of Monroe and State of New h fiuiii, he in entecl'certain new and useful n'ovements in Tractors; and 1 do hereby cl-arc the following to he a. full, clear, and description of the same, reference behaul to the eccoi'npanying I drawings, 1g it port of this specification, and to the reterence-numerals marked thereon.

he present invention relates to tractors,

end it has for its object to provide it machine honing a. novel construction and arrange- ,t for drawing plows, hzirrows, CultlVEtand other term implements, or doing rt of term or road work of this gene1 1 clmrocter.

:t'urther oloject'oi' my invention consists in providing it machine having Sufficient powerto pull com 'mretively heavy loads, and, to ascend steep grades against the ohstruetions that are usually to he encountered,

iirth and rigidity in all of its parts to withstand any strains to which it may be subjected. I

Still another object of the invention is to etloril 21 machine that can be readily controlled, end to so construct and arrange the driving; wheel as to furnish a greatly increased pulling capacity by causing a firm,

unyielding engagement between the wheel and the surface of the ground, irrespective of the character of the lettel To these incl other ends the invention consists in certain improvements and combinzitions of parts all as will be hereinafter more :tiilly'clescribed, the novel features be ing pointed out in the claims at the end of the specification.

I Th e yoke 41 30 are provided, of any suitable construc-.

tion, for controlling two forward speeds of the engine while the clutch 31 is arranged on the jack shaft 26 to control the reverse move ment of the machine, said clutches being cperated through the clutch rods 33, and 34.- respectively. The clutch rods are arranged to be operated by a single controlling lever at the rear of the machine, which is designated at 35 and is pivotally. mounted on the support 36. Said clutch rods are slidably supported on a strap 37 which is attached to the frame, and they may be alternately moved by the lever through an actuating arm 38 carried thereby, in the manner that will now be described. The actuating arm 38 extends upwardly from the lever '35 at its lower end and is arranged to engage the notches 39 which are formed in the clutch rods as shown in Figs. 6 to 9 inclusive. The lever is laterally slidable on the support 36 to enable the actuating arm 38 to engage either one of the notches 39, and is guided by the notched plate l0. l Vhen one of the clutch rods is being operated, it is desirable to lock the remaining clutch rods against .movement, and to this end I provide a yoke i1 which carries a guide rod 42 that is laterally slidable on the frame in the guides 4:3. The yoke is provided on its upper side with ears as between which is engaged an arm 4-5, pivotally connected 46 to the lower end of the lever 35, whereby the lateral movement of the lever is imparted to he yoke 4:1 to effect a corresponding movement of the latter. provided with oppositely projecting locking arms 4;? which are arranged in the plane of the notches 39 in the clutch rods and related to each other that when the actuating arm 38 is engaged with one or the clutch rods, the locking arms l7 oi the yoke are in engagement with the notches of the remaining clutch rods and movement of the latter is thereby prevented.

The tread of the driving wheel is preferably provided at its central part with a. plurality of elongated cleats %3 which are oppositely disposed, at an angle to the axis of the wheel, while all designate projections essence or teeth which are secured near the edges of the wheel, in staggered relation and spaced from the centrally disposed cleats This arrangement afi'ords an extremely efiicient gripping surface for the driving wheel, and produces the necessary engage ment with thc'surface of the ground to enable the machine to travelover most any kind of ground, and to draw the heaviest loads without any loss of power.

I. claim as my invention:

1. Atractor comprising a frame, an axle and combined steering and rolling wheels at the front, and a driving wheel having a tread as wide as the distance between the front wheels, said driving wheel being journaled near the "rear of the frame.

2. A tractor comprising an axle and combined steeringand rolling Wheels, at the front, a frame having a reduced forward port-ion arranged intermediate said steering wheels and to which the axle is attached, a driving wheel having a tread as wide as the distance between the steering wheels, said driving wheel being of the frame, an engine disposed on the frame between the driving wheel steering wheels an axle on which the driving wheel is mounted,asprocket wheel attached' to each end of the last mentioned axle, and transmission gearing connecting the engine and said sprocket wheels.

' 3. A tractor comprising a frame, an axle and combined steeriiigland rolling wheels arranged at the forward part of the frame, a driving wheel --dispoSed in rear of the steering wheels-having a tread as wide as the distance between the steering wheels, said driving wl ieel beinp; journaled in the frame at its widest part and having its edges adjacent to the sides of theframe, an enginebetween the steering wheels and the driving wheel, and transmission gearing connecting the engine and the driving wheel. a v
